| 摘 要： | 基于A股上市公司对外投资行为所构拟的资本流、人口迁徙大数据所构拟的交通流和搜索引擎指数所构拟的信息流构建“流空间”网络，对珠三角城市空间联系特征与演进趋势进行定性描述与定量分析，并对城市群内流空间网络结构进行探讨。研究表明，珠三角城市群城市体系空间结构紧紧围绕广、佛、莞、深这一南北纵深的区域发展走廊，在信息流上呈现广州、深圳双核，交通流上呈现广州、深圳与东莞三核，资本流上呈现深圳单核发展的态势；城市网络呈现显著的核心—半边缘—边缘的非均衡结构，珠江东岸成为珠三角地区功能集聚、要素流动与城镇联系的高地，在城市网络中具有较高的资源配置能力；发展要素在湾区城市间自由流动仍存阻碍，城市间呈梯度发展差异，广州、深圳不论在流要素的吸引还是输出上均大幅超出其他城市。要实现珠三角地区城市群物理层面真正的同城、协同或融合，一方面需要打通阻碍要素自由流通的壁垒，另一方面需要打造城市核心竞争力。

| Abstract: | As China's reform enters deep water and the opening-up enters a new stage, the Pearl River Delta (PRD) region, an important spatial carrier of the national location policy, has become the focus of attention in terms of improving collaborative governance capabilities within the region and optimizing the spatial system structure of urban agglomerations. In this study, a "space of flows" network was developed based on the capital flow, constructed using the foreign investment behavior of A-share listed companies, traffic flow, constructed using population migration data, and information flow constructed using the search engine index. The social network analysis method was used to qualitatively describe and quantitatively analyze the spatial connection characteristics and evolution trend of the PRD cities. The study shows that the urban system of the PRD urban agglomeration has been developed into a "space of flows" network. Additionally, it shows that the spatial structure of the urban system of the PRD urban agglomeration is closely centered on the regional development corridor of Guangzhou, Florida, Dongguan, and Shenzhen, which is deep in the north-south direction. Capital, traffic, and information flows form a network structure with Guangzhou and Shenzhen as the regional extreme nuclei. The urban network shows a significant coresemi-edge-edge unbalanced structure, and the free flow of development factors among cities in the Bay Area is still hindered, with gradient development differences among cities. Overall, the factor flow network is mainly based on Guangzhou and Shenzhen as the dual cores, with spatial differentiation among capital, transportation, and information flows, forming a more apparent network power center on the east bank of the Pearl River. By measuring the degree of centrality of information, traffic, and capital flow of each city in the PRD, Guangzhou, and Shenzhen were found to significantly exceed other cities in terms of attraction and output of flow factors. In terms of investment flow, a narrow "N" structure is formed with Shenzhen as the core node which converges toward the Pearl River; in terms of traffic flow, a wide "N" structure is formed with Guangzhou, Shenzhen and Dongguan as the core, which undulates in the middle of the Bay Area; in terms of information flow, a narrow "N" structure is formed with Guangzhou, Shenzhen and Dongguan as the core. In terms of information flow, an inverse "y" structure is formed along the east bank of the Pearl River with Guangzhou and Shenzhen as the core. Based on the empirical study findings, the development planning of the PRD urban agglomeration is discussed in the light of its actual development. To promote the deep integration of urban agglomerations in the PRD region, it is necessary to avoid zero-sum competition caused by non-market factors through institutional innovation on the one hand, and through increasing the investment in infrastructure construction and accelerating the circulation of factors on the other. In addition, the rapid response of the Internet can help cities at the geographical periphery break free from the geographical constraints of physical distance to develop faster. |
